Olivier Heudi
obtained his diploma of advanced studies in physiology and pharmacology at
Pasteur Institute Paris (France) in 1995 and his Ph.D. in life Sciences at the University of Angers France in 1999. He previously
gained experience in the analytical field at GSK Stevenage (UK) where he has
implemented LC-ICPMS and LC-MS/MS for the quantification of peptide in
biological fluids and at Nestlé Lausanne (CH) where he developed LC-MS/MS
methods for the identification and quantification of vitamins and natural
ingredients in food products and in raw materials. Then he joined Novartis
Institute for Tropical Diseases (Singapore) where he was leading the
bioanalytical laboratory. In December 2006, Olivier was appointed as laboratory
head in the DMPK group where he is now working on LC-MS/MS method development
and implementation for the quantification of monoclonal antibodies,
oligonucleotides and small molecules in biological matrixes. Olivier is active
as reviewer in several analytical papers and has great interest in new
technologies with special attention on large molecules.

Research Interest: Synthesis of anostructured materials (e.g.Gold nanoparticles, Carbon Nanotube, QDs), Assembly of biomimetic nanomaterial and photoelectric chemical analysis, Development of protein and cell based electrochemical biosensors for medical diagnostics, Fundamental Understanding of DNAs, Antibodies, DNAzymes and Their Applications as Sensing and Imaging Agents in Environmental Monitoring and Medical Diagnostics

Research Interest: Analytical Probe and Protein Biotechnology (a branch of chemical biology) Based on physicochemical principle for interactions of proteins with their ligands, chemometrics is utilized to mine information associated with the forces of their interactions, the strength for their bioaffinity interactions (affinities), the quantities of counterpart biomolecules, which facilitates the development of methods and probes for in vitro diagnostics and drug screening, protein ligands and protein mutants of biological significance. In detail, our research interest covers the following topics:

(1) New methods and probes for in vitro diagnostics and drug screening: to enhance analytical efficiency and precision, probes are designed based on mechanistic ways of bioaffinity interactions and new process to mine information are developed; such new methods and probes are applied to simultaneous assays of multiple components in single channel, especially for simultaneous immunoassays of multiple components in single channel, the screening of ligand mixtures, the screening of enzyme mutants, homogenous bioaffinity assay with tryptophan residues as resonance-energy-transfer donors, and linear response by competitive bioaffinity assay;

(2) With PDE and GST as examples, methods are developed to rational and combinatorial design of isozyme-selective inhibitors, pro-inhibitors and soft inhibitors, the screening of such inhibitors, and the potential as therapeutic agents;

(3) With uricase, arylsulfatase and alkaline phosphatase as examples, rational design and directed evolution of enzymes are studied, together with high-throughput screening and evaluation of their mutants, chemical modification of proteins; rational design of fused proteins as therapeutic agents;

(4) Affinity-labeling and site-specific immobilization of protein targets, the cross-linking/conjugation of enzymes and antibodies.
